Common Failures Of Spiral Sand Washer

A spiral sand washer is a common piece of sand washing equipment. This article outlines five frequent faults associated with spiral washing and their corresponding solutions, aiming to help you better understand the operation of spiral washers.

1. Broken Shaft

The primary causes of shaft breakage include uneven sand return, insufficient strength of the hollow shaft, unbalanced running loads on the classifier, poor quality in shaft material processing, improper installation or bending of the hollow shaft, and incorrect operational procedures. These issues can be resolved by replacing the hollow shaft or performing re-welding repairs.

2. Abnormal Vibration or Noise

If the spiral sand washing machine produces abnormal noise or vibrations during operation, immediately cease feeding materials. Once the remaining materials have been processed, shut down the generator and conduct a thorough inspection. Resume operations only after confirming that all systems are functioning correctly.

3. Damaged Spiral Blades or Bent Spokes

This issue is typically caused by excessive sand return during operation, leading to blockages in the sand return tank, or insufficient spiral lifting prior to startup. The problem can be addressed by repairing or replacing the damaged spiral blades and spokes.

4. Gear Damage

Prolonged wear can lead to gear damage. It is essential to replace damaged gears promptly and perform regular maintenance. Additionally, ensure the sand washer shaft maintains the required level.

5. Lifting Rod Vibration

Vibration in the lifting rod is often caused by a bent shaft head, sand accumulation in the lower shaft head, or worn-out balls within the shaft head. Customers should regularly clean the lower shaft head and inspect for shaft bending and ball wear in a timely manner.

This article has outlined five common failure causes and solutions for spiral sand washing machines. Beyond selecting the right sand washing machine, special attention must be paid to its maintenance and repair. Regular upkeep not only improves sand washing efficiency but also extends the equipment’s service life. Therefore, maintenance of the sand washing machine is indispensable.
